IMPROVEMENT IN LOO MS.

Specification forming partof Letters Patent No. 35,981, dated J nly 22,1 862.

.To allwho'm it 12mg] concern:

Be it known that I, WILLIAM REYNOLDS, of Manchester, in the county ofHillsborongh and State of New Hampshire, have invented certain new anduseful Improvements in Picker-Motions for Looms; and I do hereby declarethat the-same are described and represented inthe followingspecificationand drawings.

. To enable others skilled in the art to make and use my improvements, Iwill proceed to describe their eonstruction and operation, re-

ferring to the drawings, in which the same letthe side of the loom-sothat the end of the rocker will work against and under it when theshuttle is thrown;

In the accompanying drawings, A is the end of the shaft on which the layof the loom vibrates; or it may be the extension of a pivot, whichanswers the same purpose.

B is an iron rail, which may be made in the form shown, or in such otherform as will an swer the purpose. It-is provided with a hub, 0', at theside ofone end, which is perforated to receive the shaft, on which it isfastened by the set-screws D and E, and the hole in the end of the hubfarthest from the set-screws is made to fit the'shaft, and the hole iswidened in its perpendicular diameter gradually from that end to theother, as shown by broken lines F Fin Figs. 1 and 3, so that byunscrewing one screw and screwing the other the outer end of therail maybe vibrated, either raised or lowered, andadjnstedso as to make therocker G and picker-staff H throw the shuttle at the proper pitch,either high or low, as may be desired. v

The rail B is provided with a curved standard, I, at the outer end, witha groove, J, in it for the end of the rocker G to work in, while theopposite end of the rocker. works in a groove in the stand K and worksagainst the stand and roller L, as shown by broken lines in Figs. 1 and3, and as the end of the rocker descends when the shuttle is thrownit-works under the roller L, so as to bring the'curve M against theroller. and partially under it. The roiler'L is arranged to turn on thepin N in the stand K, which stand may be made in the form shown in thedrawings and fastened to the rail B by the screw 1?. l

The picker-staff H, which is represented as broken off, may be drawnforward to throw the shuttle by a strap or link applied to it somedistance above the rocker. The spiral spring S is fastened to the screwD and acts on the lever B to draw the pioker'staff back afterithasthrown the shuttle, being connected to the rocker by the strap Q.

In constructing thispioker-m otion the rocker and rail, or one of them,should be so curved that that part of the picker-staff which acts on theshuttle will traverse parallel or nearly parallel with the raceboard ofthe lay of the loom, on which the shuttle traverses, and the end of therocker which works against the roller or the stand should be so curvedthat the rocker will not slide on the rail as itis worked to throw theshuttle.

I have described the end of the hole next to the loom in the hub G asbeing made to fit the shaft; but this end may be widened and theopposite end made to fit the shaft, if preferred that way. Fig. 4 showsthe hole in the hub G widened perpendicularly.

Theabove-described device for picker-motion is simple in itsconstruction and operation, may be made cheap or at small cost, is

not likely to .get out of order, is easily'adjnsted to give the shuttlethe desired inclination or pitch, and is easy of access to theattendant.

I believe I have described and represented my improvements inpicker-motions for looms so as to enable any person skilled in the artto make and use them. I will now state what I desire to secure byLetters Patent.

I claim- I. In combination with the rockerand rail, a grooved standardat one or both ends of the rail, curved or otherwise, for the purpose ofholding the rocker on the rail when it (the rocker) is worked to throwthe shuttle, substantiall y as described. 3

2. The roller L, in combination with the grooved stand K and rocker G,for the purpose set forth, snbstantially as described.
